In order to grasp the effect of diamond trip geometries on boundary layer transition of hypersonic inlet, an experiment at Mach number 6 in a hypersonic wind tunnel was performed for a hypersonic inlet. The heat transfers at the inlet wall were measured through the infrared thermography. The transition region was judged by the comparison of heat transfer between experiment and computation. Ten diamond forced transition trips were designed according to Modern Design of Experiments. The experimental results shown that the effect order of trip geometries on transition region were the trip height, distance between diamond elements and diagonal length of diamond element from the largest to the smallest. Transition region moved forward to the model tip with increasing trip height or trip length, or with decreasing distance between diamond elements, or with increasing diagonal length of element. The optimized configuration was obtained for diamond forced-transition trip when the optimization object was transition region.
